6- Claims. 1.

The present invention relates toa folding bed, such as a chair or a sofa, with a bed frame com-- posed of a number of sections hingedly connected to each other: Folding beds of this" kind are usually made of wood, and the use of this material results in large dimensions of'the piece offurni ture. Metal constructionshave also been used to some extent, but these constructions have been complicated.

An object of theinvention is to provide a folding bed of. a simple construction comprising a few number of'parts.

Another object to reduce the dimensions of the main frame within: which the folding bed frame is located.

A further object is to obtaina folding bed which can be easily disassembled for transport and storing and which is of a low: weight.

With these and other objects in view a folding bed according to one form of the invention will be hereinafter described, reference being made to the accompanying drawing in which:

7 Figure 1- is an inside: elevation of an end per-- $1011".

Figure 2 is a top view of a sofa with end portions according to Figure 1- and only one of the two bed: frames shown in. part in the drawing.

Figure'S is a front view of and Figure 4- a side elevation of the back portion.

Figure 5- is a section according to line V-V in Figure 4.

Figure 6 is a section along line VI-VI' in Figure 3, and

Figure 7 is a side elevation of an intermediate support.

Figure 8- a section along line VIII-*-VIII in Figure. 2- of the sofa as folded.

The end portion as shown in Figure 1 is formed by bending. a single tube of steel or other metal and comprises an upper frame member I', a fore frame member 2, a lower frame member 3 and two substantially vertical frame members 4', 5 of which the member 4 is located behind the member 5 and connectedwith this member 5' by a short frame member 6' at their upper ends. Thexmembers I and 3 are substantially horizontal and parallel. The frame member I is welded to the frame member 5, and the lower end of the member 5 is welded to the frame member 3. This end: portion: is- .preferably made substantially I member 3. This member 3 passes over along acontinuous curve into the frame member 4, and the foot 8 is, therefore, located within" the extension of frame member i. The back portion is composed of an upper frame member 9" of a metal tube; the ends of which are bent so asto form two vertical frame members It I I The lower endsthereof are" welded to ametal tube [-2, the ends of which are closed by a metal plug l4 having a threaded aperture I 3. A middle cross framemember E5: of a metal tube is welded at the ends to the frame members 9 and I2 and a number of similar cross members :6 of a less diameter and preferably also of metal tubes are fastened by welding in a similar manner. The lower portions of all cr'oss members are bent forwards along a curve corresponding to that between the frame members 3 and 4' in the end portions. For connecting the back portion with the end portions it is provided at each end with two headed pins ll, which can be introduced in and lowered in corresponding perforations It in the: frame member 4'.

A perforation is in frame member 3 is located oppositeto the threaded perforation l3, in which a bolt passing through the aperture: I9 is screwedand tightened. The three connection points will thus-be located so as to form a triangle, whereby the connection between the back. portion and theend portions becomes very rigid;

The intermediate support 132 is formed by'bend'-' ing'a metal tube to a closed and plane construe-- tion and comprises an upper frame member 20 a fore frame member 21, a lower frame member 2'2 and. a rear frame member 23. A single foot 24' is welded. to the fore end of frame member 22. For connection of the intermediate support with the back portion it is provided with two" headed pins 25 to be introduced into and lowered in corresponding perforations 26 in the middle cross: frame member it; The frame: member 23 is' further provided with an aperture 48 opposite to a corresponding." aperture 21' in the frame member I=2 and. by means of a bolt, both portions can be screwed and drawn together. Also in this case the three connection points form a triangles Each one of the bed frames comprises a rear or lower U-shaped section 28' formed of a metal tube with an endframe member 2& andtwo longitudinal frame members 33 These latter are hingedly connected. with an intermediate section 31', comprising two longitudinal frame members 32- andtwocro'ssmembers 33 located at a lower plan and having upwardly bent ends welded to the frame members 32. The section 3| hingedly connected with a seat section 34, which is connected in a similar manner with a back section 49 resting on and entirely supported by the upper frame member 9 of the back portion. The back section is provided-with two bows 5B bearing against the front side of the frame member 9 and has two portable legs 5| for supporting the back section of the bed frame in unfolded position. A closed metal frame 52 is removably fastened to the longitudinal frame members 34 of the seat section and is at the rear end bent upwards so as to form a bow. To this bow a lower back cushion '53 may be fastened, and the horizontal ortion may carry an upholstery indicated at 54. A removable frame 55 rests on the upper end of frame 52 and carries an upper back cushion 56. At least all the peripheral frame members are made of metal tubes.

Each of the frame members 32 is provided with headed pins 35 introduced in corresponding perforations 35 in the end portion and 31 in the intermediate support whereby the bed frame is pivoted in the main frame of the sofa. Flanges 38 with apertures 39 are welded to the inside of the longitudinal frame members for fastening a resilient bed bottom of any suitable type.

When the bed frame is turned to its unfolded position as shown in Figure 2, the end frame member 29 rests on the upper portion of two guide members 40 welded each to a cross member l6 and to the lower frame member I2 of the back portion. The lower portion of the guide members 40 is bent to a hook 4|, and when the bed frame is being folded together the frame member 29 slides on the guide members 40 unto u a lower end position, where it is retained by the hook 4|.

For further supporting of the end section 28 in unfolded position of the bed frame the upper frame member 20 of the intermediate support is provided with a bolt 43 passing through the frame member 20 and having a handle at its upper end, whereas its lower end is provided with a cross bar which after turning 90 from the po sition shown in Figure '7 supports from below the frame member 30 of the end section. For supporting the outer frame member 30 a vertical pivot 45 passing through the member 30 has its upper portion 46 bent at a right angle so as to rest in its locking position against the upper frame member I. Secured to the portion 46 is a plate spring 4! extending above and along the frame member I. When the bed frame is to be folded the pivot 45 is turned by means of the spring 41 an angle of 90, whereby the section is released from the frame member I and the spring 41 will extend over the bed in order to keep the same in its position, when the bed together with the bed frame is folded together.

It is obvious that the invention as well can be applied to a chair having only one bed frame. In this case the intermediate support 42 is removed and the back portion is shortened to half of its length. Also other modifications may be possible without departing from the scope of the invention.
